Seems like I need to build everything without ever having to close the dialog. if I do close, when I reopen, and try and save after I have changed something I generate a backup file. This seems kinda limiting. I would like to reopen a project, to change parameters, or do you just change the parameters via the xml file thereafter? The wizard is only for creating brand spanking new add-ins, not necessarily modifying existing add-ins. Does this make sense?
